Abstract: 1531268 Splints G W JOHNSON 15 Dec 1975 51308/75 Heading A5R A tubular splint or body part casing comprises two shell members 12, 14 which can be adjustably fitted one within the other to enclose the body part, means 44, 54, 57 for securing the members together and circumferentially disposed inflatable pneumatic cells 30 which in use are disposed between the shells and the body part. The shell members 12, 14 are generally semi-cylindrical and made of thermoplastic material, apertures 24 arranged in columns longitudinally of the members and runs circumferentially of the members being so spaced that they may be easily flexed about longitudinal axes so that the side edges of one member 14 may be disposed between the side edges of the other 12 when the members are disposed about a limb. Air bags 30 having air inlet tubes 32 are disposed against the inner surface of each member and are inflated to space each shell member from the limb. The outer surface of each bag 30 may be covered with an absorbent material to aid ventilation. In use, the shells are intended to make indirect abutting engagement with the limb in selected regions i.e. the shell engages the limb indirectly through an intermediate layer or layers of material other than fluid e.g. portions of the pneumatic cells in flattened condition.

Title: Distortion reduction in data transmission systems
IPC: H01P1/00
Filed: 1974-11-29
Abstract: 1460954 Data transmission; distortion reduction; directional couplers INTERNATIONAL BUSINESS MACHINES CORP 29 Nov 1974 [26 Dec 1973] 51735/74 Headings H4P and H4R To improve reception fidelity of zero D.C. level biphase signals transmitted by line a stripline coupler is incorporated in the line physically separating it into first and second lengths, the coupling characteristic of the coupler being expressable in terms of where T is the coupling length and Vin, Vout, S and n have conventional significance, 4T being equal to the distance travelled by a wave front in the Coupler in a single bit time and K#0À5. Directional coupler 15 with parts 16, 18, connected reverse directionally is connected in series with a transmission line to a receiver 14. The coupling produces a signal having a substantially fixed width regardless of the length of the line, and signal height which diminishes comparatively slowly with length traversed. The coupling coefficient must be at least 0À5 and an electrical length T substantially equivalent to  bit time supplied by signals whereby at least one type, e.g. 1's has an equal positive and negative excursion. Types of signals envisaged are bi-phase, both square wave and sinusoidal also those in which bits of one type are represented by zero potential. In an alternative arrangement, the height of the second "eye" in the tested characteristic may be increased by a factor of 1À5 by employing a second directional coupler either in the line or at the transmitter end. This does not effect the width of the eye pattern and is stated to enhance extraction of clocking information from data by increasing the slope of the second pattern. Employment of further couplers is envisaged in the Specification. The coupler (Fig. 2, not shown) may be of strip line type having two parallel adjacent printed circuit strip lines separated by dielectric also separated from and located between thin copper sheets forming ground planes, both strips being terminated at one end by resistors (26, 28). It is stated that tolerances on cable characteristics can be relaxed as signals transmitted are more dependent on signal frequency than cable characteristics which is particularly useful in "looped" systems. To extract information from transmitted signals, these may be strobed on reception preferably in the second half of the data waveform.

Brushes 21 at the sides of an elongated suction opening 12 in a suction cleaner nozzle 10 are secured to diaphragms 16 beneath spaces 14 communicating with the suction conduit 13 via openings 15, so that when the nozzle 10 is applied to a soft surface, such as that of a carpet, the said surface substantially closes the suction opening 12 so that the suction in the conduit 13 and the spaces 14 is sufficient to raise the brushes 21 from said surface. When, however, the nozzle 10 is applied to a hard surface, supports such as wheels 26 hold the nozzle opening away from that surface so that the suction in the conduit 13 and the spaces 14 is insufficient to raise the brushes 21, which are held against the hard surface by springs 18. Alternatively the suction opening 12 may be circular and surrounded by a single angular brush. In a further embodiment the suction conduit 13 is provided with an opening, or a conduit communicating therewith, provided with a shutter device for varying the suction within the conduit 13.

Title: Method of fusion-bonding parts together

Filed: 1971-11-17
Abstract: 1350802 Welding by fusion; bonding metallic sheets BENDIX CORP 17 Nov 1971 [27 Nov 1970] 53431/71 Headings B3R and B3A A process for fusion bonding parts of a metal having a "freezing range" (i.e. a temperature range in which both liquid and solid states coexist) comprises positioning said parts so that interfacing surfaces thereof are in contact, and heating said parts to a temperature within said freezing range and maintaining said temperature until bonding occurs. The parts may be thin sheets bonded to form a laminate, as for formation of fluidic elements in which the sheets have flow passages formed therein. Preferably, the parts are heated to only slightly above the solidus line, with 0À01 to 25% by weight of liquid present. Preferably, also, the part material comprises alloys or mixtures having a large freezing range so as to avoid the need for close temperature control. One sheet bonding process example sequence comprises (1) deoxidation of the interfacing surfaces; (2) stacking of the sheets in a vacuum furnace, the vacuum preventing re-oxidation and holding pressure being sufficient only for accurate sheet registry; (3) heating of the sheets into the freezing range; (4) removal and cooling of the laminate thus formed; and, if required, (5) heat-treatment and/or age hardening. The vacuum in the furnace may be replaced by a neutral or reducing atmosphere. In a specific example of bonding aluminium alloy parts, the latter are, sequentially, cleaned in a solution such as sodium hydroxide, rinsed sequentially in water, nitric acid solution, water, and alcohol, assembled and placed in a vacuum furnace and bonded at 525‹ C. at less than 10<SP>-4</SP> Torr for 10 minutes.
